Preparing for a police chase

Before you start: steal the car in the first place, so the police can't just run the plates and ID you.

In a rural area: take your truck off the paved roads where the police cruisers can't follow you.

In an urban area: do something so dangerous that the police can't follow you without endangering lots of innocent people. I once saw a guy get away by going the wrong way up an exit ramp. In some neighborhoods there are enough turns and little enough traffic that you can escape by getting two blocks ahead of your pursuer.

Once the helicopter is on you: parking garage/mall is a good one. Fleeing on foot in a forested area will give you pretty good cover. Stop under an overpass, carjack another car, and leave. I forget which movie that was from.

oh, and I'd be careful about fleeing on foot from helicopters as a number of them are equipped with infra red cameras and will play the "getting warmer, getting colder" game with other police on foot until they find you. I saw it on tv.
